CLOTHE S FASTENERS Filed Dec. 16, 1964 Sheets-$heet United States Patent6 Claims. oi. 24-421 This invention relates to a hook joint forfasteners for clothes, particularly for waistband fasteners of the typecomprising a hook and an eye.

Hook-and-eye fasteners are known, which are secured to the fabric byprongs, which are pierced through the fabric and preferably bent againsta backing plate. In these fasteners, the hook member comprises abaseplate carrying a reversely bent hook portion. The baseplate carriesalso the prongs, which are pierced through the fabric and reversely bentagainst the backing plate. In these known fasteners, the hook portiontends to be forced against the baseplate, particularly in the ironingpress and must be bent open so that it can be inserted into the eyemember.

In the hook joint according to the invention, this disadvantage isavoided in that a crosspiece which extends transversely to the hookportion and serves for engaging the fabric is offset adjacent to theaperture of the hook portion and, if desired, on both sides of the hookportion and merges with the hook portion. The hook portion extends fromthe region where it merges with the crosspiece freely over saidcrosspiece. The backing plate is preferably oppositely offset in theregion in alignment with the offset crosspiece. Such a hook member hasno reversely bent edge and can no longer be compressed. Besides, it isflatter than the previously known hook members.

The offset crosspiece may be provided with a struck-off prong, which hasbeen cut from the hook member in the direction in which the hook portionis inserted, and/or the hook member may comprise one or more prongs,which have been struck off in the direction opposite to the direction inwhich the hook portion is inserted. The last embodiment is capable oftaking up particularly high tensile stresses. Besides, the offsetcrosspiece may be provided with prongs which have been struck off fromthe transverse direction of the hook portion and extend on both sidesthereof, or such prongs may be disposed on both sides of the hook andinclined to the longitudinal direction of said hook.

Finally, the hook portion, is defined by a V-shaped strip having acentral opening and thereby defining a tongue which projects above theoffset crosspiece. This will result in a particularly flat andesthetically desirable form of the hook portion.

Various embodiments are shown by way of example in the accompanyingdrawing, in which FIGS. 1 to 3 are perspective views showing a first embodiment of a hook-and-eye fastener provided with a backing plate.

FIGS. 4 and 5 are central sectional views taken through the hook memberand the backing plate assembly of the embodiment shown in FIGS. 1 and 2.

FIGS. 6 and 7 are side and end elevation views showing the hook memberof FIG. 1.

FIGS. 8 and 9, respectively, are a central sectional view and anelevation showing another embodiment of the hook member.

FIGS. 10 and 11, respectively, are a central sectional view and anelevation of the backing plate for use with the hook member of FIGS. 8and 9.

FIGS. 12 and 13, respectively, are a central sectional 3,323,187Patented June 6, 1967 view and an elevational showing two furtherembodiments of hook members.

FIGS. 14 and 15, respectively, are a central section view and anelevation of the backing plate for use with the hook member of FIGS. 12and 13.

In the first embodiment illustrated in FIGS. 1 to 7, the hook membercomprises a hook portion 1 which is in the form of a tongue constitutedby a V-shaped strip member having a central opening. The strip 1 hasbase portions 1 which are joined by an offset crosspiece 2. Thecrosspiece 2 is deformed downwardly with respect to hook portion 1 andbetween the base portion 1 thereof a prong 3 extends from the crosspiece2 at an end thereof closer to the free end of the hook portion 1. Thehook portion 1 extends over the crosspiece 2. At the rear end of thebase portion 1' of the hook portion, the prongs 4 and 5 have been bentdownwardly. The prongs 3 to 5 are then pierced through the fabric 6 andbent against a backing plate 7, which is formed with holes 8, 9, and 10forming passages for the prongs, as is shown in FIGS. 1 and 2. Thebacking plate 7 is deformed upwardly at 11 between the holes 8 to 10 toprovide sufficient space for receiving the prongs. The hook portion 1 isreceivedby a known eye 12, which is secured to the waistband fabric 16and provided with piercing prongs 13, 14 and a backing plate 15. This isshown in FIG. 3. FIGS. 4 to 7 show in section and elevation the hookmember 1 and the backing plate 7 of the first embodiment with projectionlines a, b, and c. As is apparent from these figures, the curvedperipheral rim 7a of the backing plate 7 extends around the periphery 1aof the hook portion 1, the height of the rim 7a corresponding at leastto a portion of the free width between the backing plate 7 and thetongue 1 which form jaws for engaging the eye 12. The crosspiece 2extends downwardly with respect to the tongue 1, and the backing plate 7has an upwardly deformed portion 11. The deformed portion 11 of thebacking plate 7 defines a space therebeneath which correspondsapproximately to the thickness of the prongs to enable accommodationthereof with the outline of the backing plate.

In the second embodiment shown in FIGS. 8 to 11, the hook member isformed with tongue 17 and crosspiece 18 from which extend piercingprongs 1-9 to 21. Between the base portions 17 of tongue 17 thecrosspiece 18 is deformed downwardly. The prong 19 is disposed at theforward end of crosspiece 1 8 and extends downwardly. The prongs 20 and21 are formed on both sides of the crosspiece 1 8. The backing plate 22is provided with corresponding passage openings 23 to 25 and upwardlyoffset deformed portions 26 between said openings.

In the third and fourth embodiments shown in FIGS. 12 to 15, the hookmember is formed with tongue 27 and crosspiece 28 from which extendpiercing prongs 29 to 31. The crosspiece is deformed downwardly betweenthe base portions 27' of the tongue 27. The prong 29 is disposed at therear of crosspiece 28 and the prongs 30 and 31 are formed at both sidesof the crosspiece 28. The backing plate 32 has corresponding passageopenings 33 to 35 with intervening, upwardly directed offset portions36. The lateral prongs 30, 31 may be inclined, as is indicated indash-dot lines in FIG. 13 at 30' and 3 1'. In this case a backing plate32 with inclined passage openings 34 and 35' is used, as is also shownin dashdot lines in FIG. 15. As is apparent from FIG. 15, the periphery27a of the hook portion 27 is located within the rim 32a and may vary,as with respect to rim 32a, or be substantially uniform, as with regardto rim 32'.

What I claim is:

1. A hook fastener adapted for being attached to material and engagedwith an eye, said fastener comprising a hook member including a tongueconstituted by a V-shaped strip member defining a hook portion, acrosspiece member connected to the strip member at the spaced endsthereof, said crosspiece member being deformed and having a portionoffset with respect to said hook member such that the latter projectsthereover, and prongs extending from said crosspiece member in the samedirection in which the crosspiece member is ofr" set from the hookportion, a backing plate, said backing plate having openings forreceiving said prongs which are inserted through material and bent overthe backing plate to secure the hook member to the backing plate withthe material interposed therebetween, said backing plate including adeformed portion proximate said opening extending towards the hookmember and defining a space for the accommodation of the prongs.

2. A fastener as claimed in claim 1 wherein said back ing platecomprises a peripheral rim which extends in the same direction as saiddeformed portion thereof.

3. A fastener as claimed in claim 1 wherein the space defined by saiddeformed portion is approximately equal to the thickness of the prongs.

4. A fastener as claimed in claim 1 wherein said tongue defines acentral opening, said offset portion of the crosspiece member beinglimited to the transverse extent of the central opening.

5. A fastener as claimed in claim 4 wherein said strip has base portionswhich merge with the crosspiece member.

6. A fastener as claimed in claim 1 wherein said deformed portion of thebacking plate and the offset portion of the crosspiece member are inalignment with one another.
